Doritaenopsis plant named ‘Sogo Linluo’

ABSTRACT

A new and distinct cultivar of  Doritaenopsis  plant named ‘Sogo Linluo,’ with flowers of light yellow overlaid with pink toward base and a purple red labellum, freely flowering habit, upright, freely branching and sturdy flowering stems, and excellent postproduction longevity.

FIELD OF THE INVENTION

The present invention relates to botanical classification/cultivar designation: Doritaenopsis Orchid cultivar Sogo Linluo.

BACKGROUND OF THE INVENTION

The present invention comprises a new and distinct cultivar of Doritaenopsis Orchid, a bigeneric hybrid of Doritis×Phalaenopsis, both of the family Orchidaceae, and hereinafter referred to by the cultivar name, ‘Sogo Linluo’. The genus Doritaenopsis is also a member of the family Orchidaceae.

Doritaenopsis comprise a group of bigeneric hybrids generally intermediate in character between the parent genera, which are suitable for cultivation in the home or greenhouse. The parent genera of Doritaenopsis are predominantly epiphytic or rock dwelling, and are native to tropical Asia, Malay Archipelago, and Oceania. The species typically have 2-ranked fleshy oblong or elliptic leaves affixed to a short central stem (monopodial growth), which vary in size from 5 to 8 inches to over 2 feet. The leaves may be entirely green or mottled with silver grey.

Doritaenopsis orchids, often referred to as “Moth Orchids” in the horticultural trade, are frequently used to furnish cut flowers for the florist trade, or sold as flowering potted plants for home or interior plant scapes.

Doritaenopsis produce upright racemes, often with many showy flowers, which open in succession beginning with the lowermost. The flowers possess three sepals, and three petals, the lateral ones being alike. The lowermost petal, called the labellum, is three lobed and is often more brightly colored than the other flower segments. Flower colors are frequently various shades of pink, white and yellow.

Doritaenopsis orchids are typically propagated from seeds. However, Doritaenopsis is capable of being asexually reproduced from offshoots, which frequently arise from the lower bracts of the inflorescence. The resulting plants are detached from the mother plant and may be planted in a suitable substrate.

‘Sogo Linluo’ is a product of a planned breeding program conducted by the inventor in Kaohsiung County, Taiwan. The objective of the breeding program is to create new uniform pot-type Doritaenopsis Orchid cultivars having attractive flower coloration. The inventor had been addressed himself to the Orchids breeding since 1985.

‘Sogo Linluo’ was discovered by the inventor from within the progeny of a cross-pollination of one Phalaenopsis Orchid and one Doritaenopsis Orchid on Feb. 1999, in a controlled environment in Kaohsiung County, Taiwan.

Asexual propagation by tissue culture in a laboratory in Pingdong County, Taiwan has been used to increase the number of plants for evaluation and has demonstrated in a controlled environment in Kaohsiung County, Taiwan that the unique combination of characteristics as herein disclosed for the new Doritaenopsis Orchid are firmly fixed and are retained through successive generations of asexual reproduction.

SUMMARY OF THE INVENTION

The following traits have been repeatedly observed and are determined to be basic characteristics of ‘Sogo Linluo’ which, in combination, distinguish this Doritaenopsis Orchid as a new and distinct cultivar:

-   -   1. Light yellow flowers overlaid with pink toward the base and         the purple red colored labellum.     -   2. Freely flowering habit.     -   3. Upright, freely branching and sturdy flowering stems.     -   4. Excellent postproduction longevity.

Plants of ‘Sogo Linluo’ differ primarily from plants of the parent cultivars in flower color. Currently, there is no commercial cultivar known to the inventor to which ‘Sogo Linluo’ can be meaningfully compared.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

‘Sogo Linluo’ has not been observed under all possible environmental conditions. The phenotype may vary significantly with variations in environment such as temperature, light intensity, fertilization and day length without any change in the genotype.

The observations and measurements describe plants grown in Kaohsiung County, Taiwan under the conditions, which approximate those generally used in commercial practice.

In the following description, color references are made to The Royal Horticultural Society (R.H.S.) Color Chart.

Plants used for the aforementioned photographs and following detailed botanical description were 18 months in maturity and grown in 13 cm pots, in a controlled greenhouse with day-night temperature around 25-18 degree Celsius, and light intensity between 15,000-20,000 lux natural light, in Kaohsiung County, Taiwan.
